GASOLENE-ENGINE.

Application led January 4,

To all 'whom 'it 'may concern:

Be it known that I, JOHN C. JOHNSON, a citizen of the United States, residing at Randalia, in the county of Fayette and State of Iowa, have invented a new and useful- Improvement in Gasolene-Engines, of which the following-is a specification'.

This invention relates to a gasolene engine of the rotary type, and one of the main objects of the invention is to provide in an engine of this kind means for admitting pressure, by the expanding of an explosive compound, to several portions of a suitable disk at one time.

The invention consists in the novel features of construction, arrangement and combination of parts hereinafter fully described, pointed out in the claims and shown in the accompanying drawings, in which `Figure l is a section on the line l-l of Fig. 2. Fig. 2 is a plan view, a portion.

Fig. 3 is an end elevation. Fig. 4 is a section on the line 4 4 of Fig. 3. Fig. 5 is a rear elevation. F ig. 6 is an enlarged sectional view illustrating a'pump and inlet valve. Fig. 7 is a detail sectional view illustrating a valve connection between the pump vand the explosive chamber. Fig. 8 is a detail view partly in section and partlyk in elevation illustrating a valve arrangement between the explosive chamber and a compart ment communicating with a rotatable disk or piston.

In constructing the engine, I employ a casing 1 cylindrical in form and through which passes transversely and centrally a shaft 2. This shaft has keyed upon it a disk 3 which rotates in the cylinder 1' and the disk has upon its periphery a plurality of slightly curved teeth 4, the space between said teeth forming pockets into which an explosive mixture is admitted, after being exploded in a compartment having communication with the casing 1. Upon the rear side of the cylindrical casing l is a horizontally arranged casing 5 which is divided into two compartments by a partition 6, said partition being parallel to the shaft 2. This divides the casing 5 into two compartments which will be designated as A' and B.

The compartment A is the compartment into which the compressed air and gas is forced and in which it is exploded, and the compartment B receives the exploded mixture through a pipe7 and passes it through Specification of Letters Patent.

a port 8 into a circumferential bore 9 formed in the lower portion of the casing 1 and which communicates through a number of by-passes 10 with the pockets between the teeth 4, exhausting through an exhaust pipe 11.

To compress thel mixture, I provide a pump consisting of a cylinder 12 a piston 13. and a piston rod 14 which is pivotally connected to a gear wheel ldriven by a pinion 16 Iixed upon the shaft 2K. The cylinder 12 has at its upper end an extension 17 by one side of which is arranged a valve casing 18 and a feed pipe 19 supplying the explosive mixture opens into the valve casing 18 and a sprin drawn check valve 20 controls passage o the mixture from the casing 18 into the extension 17 of the pump cylinder 12. A pipe 21 leads from the upper end of the cylinder 12 and opens into the explosive compartment A of the casing 5 through a valve box 22, a spring controlled check valve 23 regulating the admission of 'the compressed mixture from the pipe 21 to the compartment A, the said valve being oppositely arranged with respect tothe valve 2O of the pump.

A suitable igniting plug 24 is carried by the casing 5 and extends into the compartment A. The pipe 7 which leads from the compartment A to the compartment B communicates directly with the latter compartment but has communication with the compartment A through a casing25 divided intor two parts vby a partition 26 in whichy is formed a port 27 controlled by a valve 28 carrying a valve stem 29, said stem being operated by a cam groove 30 formed in a gear wheel 31 which wheel meshes with a pinion 32 fixed upon the shaft 2. Upon one side of the partition 26, the casing 25 opens into the compartment A and upon the other side into the pipe 7.

The operation of the device is as follows: The downward movement of the piston 13 will open the valve 20 and draw in a charge of gas and air through the pipe 19 and upon the up stroke of said piston, the valve 20 will be closed and the charge will be compressed and forced through the pipe 21 through the valve 23, which opens inwardly and into the compartment A. The charge is exploded in this compartment and passes through the port 27, the cam groove 30 having moved the valve 28 into open position, and the products of combustion pass Patented Nov. 16, 1909.

through the pipe 7 into the compartment B, and thence through the inlet port 8 into the bore or assage 9 and through the bypasses l0 w ere it acts upon the teeth 4, finally esca ing through the exhaust 11.

1. In a gasolene engine avertically arranged cylindrical casing, a shaft passmg transversely therethrough, a toothed disk fixed upon said shaft,` a horizont-ally extendin casing upon the rear side of the vertica casing, the horizontal casing being arranged beneath the shaft, a partition parallel to said shaft dividing said horizontal casing into two compartments, means for admittlng an explosive mixture under pressure to one of said compartments, means for exploding. the said mixture in said compartment and a valve controlled pipe leading from said compartment to the other compartment7 the last mentioned compartment opening into the said vertical casing, thereby admitting. the exploded gases to the said disk, as Land in the manner set forth.

2. A gasolene engine consisting of a vertical casing, a shaft passin therethrough, a toothed disk upon said sha t and within the vertical casinglgg,f the said casing having a circumferential bore extending throughout its lower portion and communicating at va- .rious points with the interior of the casing,

and having an exhaust opening upon yone side, a horizontally extending casing arranged upon one side of. the vertical casing and below the shaft, a pump mounted above said horizontal casing, said ump being driven from the shaft and supp ying a compressed explosive vapor to the horizontal casing, the said -casing being divided into two separate compartments, one of which receives the explosive mixture from the pump and the other of which communicates with the bore of thevertical casing, and a valve controlled pipe connecting the two compartments.
